7th Grade Class Studies mass

Science teacher Paul Pennoyer’s 7th grade class was learning how to calculate the density of water. Pennoyer taught his class how to use a triple-beam balance and how to use a scale.

The students followed directions given by their teacher.

Then they divided each calculation to get the density. Credit: Laura Fitzgerald for Manchester Essex Multimedia OnlineA student was figuring out how to calculate the problem with a calculator. Each student was allowed to use a calculator to find the density.
